Method for determining refractory specimen heat resistance
(Springer, New York, 2008)
The most important properties governing the operation of refractories are refractoriness, service temperature and heat resistance. The heat resistance of specimens based on Al2O3 is determined by a standard laboratory ...
Stability of chromium(III)-oxide sol in the presence of inorganic anions
(Trans Tech Publications Ltd, Durnten-Zurich, 2000)
Stability of chromium(III)-oxide sol upon the addition of various electrolytes (chloride, sulfate, and ferrocyanate) was studied by a potentiometric titration method. The critical coagulation concentration was determined ...
Synthesis and settings behavior of alpha-TCP from calcium deficient hyroxyapatite obtained by hydrothermal method
(Natl Inst Optoelectronics, Bucharest-Magurele, 2007)
The aim of this work is the investigation of alpha-tricalcium-phosphate (alpha-TCP) formation from calcium-deficient hydroxyapatite (CDHAP), synthesized by hydrothermal method from CaCl2, EDTA, NaH2PO4 center dot 2H(2)O ...
Spatial and temporal distribution of pollution indices in marine surface sediments-a chemometric approach
(Environmental Science and Pollution Research, 2021)
Concentrations of As, Cd, Cr, Cu, Hg, Mn, Ni, Pb, Zn, and Fe measured at forty locations in the Boka Kotorska Bay were used to monitor the spatial and temporal quality of sediment and to assess surface sediment contamination ...
The problems in design and detailed analyses of energy consumption for biodiesel synthesis at supercritical conditions
(Elsevier, Amsterdam, 2009)
The main goal of this study is analysis the existing and recently published data related to design of larger scale plant for biodiesel synthesis at supercritical conditions. Such analysis was focused on the problem of ...
Efficiency of oil removal from real wastewater with different sorbent materials
(Elsevier Science Bv, Amsterdam, 2007)
The aim of this paper was to investigate the efficiency of different sorbent materials for oil removal from wastewater. Two types of sorbents were investigated: organic (loose natural wool fibers (NWF) and recycled wool ...
Izrada termoplastičnih kompozitnih cevi metodom namotavanja, I : opis eksperimenta / Fabrication of Thermoplastic Composite Pipes Using Tape Winding Process, I : Experimental Procedure
(Društvo inženjera plastičara i gumara, 2005)
Odlučujući faktor prilikom zamene konvencionalnih materijala sa kompozitima su troškovi. Dok cena sirovih materijala obično opada sa porastom potražnje, kod kompozita je potrebno smanjiti troškove proizvodnje automatizovanim ...
Zeolite/Chitosan/Gelatin Films: Preparation, SupercriticalCO2Processing, Characterization, and Bioactivity
(Wiley, 2022)
Chitosan/gelatin and chitosan/gelatin/zeolite films prepared by solvent casting method were impregnated with a mixture of thymol and carvacrol using a green solvent, supercritical carbon dioxide at 35 °C and 30 MPa, during ...
Crystallographic, spectroscopic, thermal and computational studies of polymeric cobalt(II)-mellitate complex with 2,2 '-bipyridine
(Elsevier B.V., 2022)
Orange single crystals of new polymeric cobalt(II) complex {[Co(bipy)(H2O)(4)](2)[Co(mu-mell)(H2O)(2)].10H(2)O}(n), 1, were synthesized by slow evaporation method at room temperature (bipy = 2,2 '-bipyridine, mell = hexaanion ...
Supercritical carbon dioxide extraction of sesquiterpenes from valerian root
(Elsevier Science Bv, Amsterdam, 2007)
Supercritical carbon dioxide extraction of sesquiterpenes from valerian root was investigated. Extractions from cultivar Arterner zuctung and two wild grown valerian subspecies were performed. The influence of extraction ...
